Notes:
The aim of this study was to synthesize yttrium/hydroxyapatite(Y/HA) nanoparticles andsubmit to a structural, chemical and biological characterization. The microstructure, shape and size,concentration of yttrium released in water were characterized using X-ray diffraction (XRD),transmission electron microscopy (TEM) and Inductively coupled plasma (ICP). The biologicalactions were evaluated by the cell cultivation method and oral bacterial colony counting method.The results showed that yttrium can be incorporated into the hydroxyapatite structure. Sizes of thenanocrystals were less than 100nm. The shape was needle-like. The human periodontal fibroblastgrowth was accelerated and oral bacterial growth was lightly restricted. The data indicate that thehydrothermally synthetized approach can be successfully used to prepare yttrium/hydroxyapatitenanocrystals with crystallinity, crystal dimensions, structure and stability close to thosecharacteristic of biological apatite and with better biological activity, bacteriostasis
